Before quarantine, the PM2.5 in the air for china was extremely high. People with asthma had a lot of problems and people had to wear a mask. Before quarantine, there were also a lot of factories producing this PM2.5 and not thinking about how unhealthy this is to breathe in. After quarantine, a lot of fast food places closed, less factories were open, and less people were driving from place to place . After quarantine, PM2.5. levels also went down a lot and people in China were not having as much difficulty breathing. This shows that some of the things making PM2.5. are: Factories, cars, and fast food places. To solve this issue, people could eat healthier and not go to fast food places all the time. Fast food places tend to produce more PM2.5 when there are more people ordering there. Another way to help with this issue would be to use different ways of transportation, like a bike or scooter. A final way to help with this problem is to have less factories in a given area. The more factories open in a state, the more PM2.5 in that state.

when the virus was no happing in china the levels of PM2.5 were very high and was not healthy for the average person to breath this type of air also a lot has changes since the virus occurred because that meant that a lot less people are outside also non essential business were closed and those business were also emitting a lot of pollution into the air. Now cars are also damaging the air significantly and riding a bike or walking or riding an electric scooter would help these air quality levels improve and that would be better for everyone in china

Before Covid-19, The PM2.5 in chin'as air was over the roof. It was super unhealthy and could have easily made a big decline in some population. Ever since Covid-19 has occurred, the levels went down due to everyone staying home and not using cars and manufacturing companies. This could have potentially been the start of a new, healthy, environment for China because I am sure the quality and the way the breathe must have felt so much better and safer than China has ever had before. Due to all China's manufacturing companies and what not, the pollution/PM2.5 has been incredibly high. The least they could do is relocate to other parts of China, Preferably other countries, and be as spread out as possible. No, this would not solve the problem fully, However it will at least reduce some of the PM2.5.

Wuhan, China's PM2.5 levels before the quarantine were pretty high. Considering how big of a city Wuhan is, it's bound to be high. I think that they could learn from the pandemic, to try to lower the PM2.5 levels. They could use less cars, for instance by taking a bus or a train to work instead. They could also cut back on the usage of gas and instead opt for more electric factories or motors.

The air quality before the quarantine was terrible, it is clearly proven in numerous articles. When we went into quarantine, only then did the air quality start improving. Something we can do to improve air quality is travel less often, or only when needed. If not, try to take public transportation instead of each individual car.

Before all of this happened, China's PM2.5 levels were extremely high and unhealthy.  During quarantine, lots of big factories and buildings closed, making the air better and lowering there PM2.5 levels. After quarantine, the air was noticeably much healthier and cleaner for the residents. All of this shows that China's use of big factories, coal factories, and buildings (lots of cars,) causes all of the air pollution in the air and the high levels of PM2.5. One way that we can maintain the pollution levels and keep them down for good would be to stop the use of coal factories for good, and use better eco-friendly factories (Waste-free energy use.) This would help China with there pollution and PM2.5 levels, and would significantly lower them. They could also stop putting so much bad stuff in the air, by maybe car-pooling to work, or riding bikes to your job.

The PM2.5 levels in Wuhan, China were extremely high prior to quarantine, and they've decreased dramatically since they've been on lockdown. Considering this, the thing causing all that air pollution was stuff people used, like cars and buses and other forms of transportation that give out gas, multiple factories being in an area, etc. So, some ways keep these levels down is by using more resourceful forms of transportation like bicycles instead of cars all the time.

Pre quarentine, the air in China was super unhealthy due to PM2.5. This made it so the air was made up of tiny particles and made the air hazy. This could cause breathing problems for your lungs. However, once quarentine started, people stopped commuting and big buildings shut down, meaning the air stopped being so polluted and the PM2.5 levels decreased. My solution would be to cut down on how much gas or energy is emitted daily, to try and stop the pollution in general.

# data[].attributes.body
Before the Pandemic happened the PM2.5 levels were astronomically high and were very dangerous for those who lived in Wuhan, China.The use of factories and driving cars everywhere we go and not being eco friending with what resources we use. This is causing a major strain in our air quality. But because of this COVID-19 and the worldwide quarantine that was put in effect and everything closing down, The levels reached even the most healthiest point which is where the air quality is up to WHO guidelines. The solution is if we could find a way to use our resources in a more eco friendly way and limiting the amount of pollution that is being emitted.

# data[].attributes.body
Air pollution has always been a massive problem within the world, especially in the recent years. We've all become so used to the factories around us, to driving cars regardless of whether they're good or not, and to not being conservative with our resources, and it's caused a lot of air pollution. One of the biggest examples of this is Wuhan, China, who's PM2.5's levels were extremely high and dangerous early in the year. However, with the threat of the COVID-19 virus, and a lockdown in place, people were forced to stay inside, which actually decreased the pollution levels. This proves that a solution to this problem is to limit how much pollution you cause, from doing things like using travel alternatives besides cars, closing down some factories, etc.

In Wuhan, the PM2.5 levels were very high, at an unhealthy level before quarantine. The air was unhealthy to breathe in, and since quarantine began the air had gotten better to breathe in, and way more healthier. Once COVID-19 had shut down the majority of areas and other populated places, things like jobs and traffic had declined. It tells you where the air had come from, and since quarantine it had dropped down because there is less of it.

# data[].attributes.body
The PM2.5 levels before COVID-19 lockdown in Wuhan, China were very high and very unhealthy. This could cause breathing problems and asthma attacks. But since lockdown, the air quality has gotten way healthier due to the fact that not a lot of people were on the streets and a lot of businesses that effected this air quality closed for quarantine. To limit this pollution of the air we could close harmful factories, use travel other than gas cars, or even just car pooling to slim down the amount of cars on the road.

# data[].attributes.body
The PM2.5 was high before the lockdown from COVID-19 because they are many travel with their cars.  At that time the air quality was very unhealthy to breathe. During the lockdown the lockdown the PM2.5 levels have decreased a lot because there less people travel with cars. When is happened the air quality was better, and the air are clean to breathe in.

# data[].attributes.body
Do to the lockdown, air quality has gotten better. When quarantine is over, PM2.5 will rise up in places that can get high amounts of PM2.5 because of how many people wish to leave their houses and a lot of people like to travel so finding a solution to have the air quality around the world is like writing an argument essay with no proper meaning. It is something that humans need to work around or deal with, and I think no matter what we do to change the air quality to be healthy, we will still have a small amount of unhealthy air, because we have cars to take us from one place to another and back and mainly it would take years or months maybe days to get to New York from someplace in Canada. Trucks help move heavy material to a store, power plants, factories, nuclear power plants. Humanity made a lot things to help make life easier. So decreasing the air quality to be healthy would take years, do to how people take in certain thing and with the american people having a lot of problems on their plates we will slowly work on air quality being healthy but we have to be careful with how we change this, plus this lockdown has helped with the air quality being good but when this lockdown is over maintaining healthy air would be a big challenge that not all 7.7 billion people would participate in.

Before quarantine the PM2.5 levels were high. Now during quarantine since not that many people are out driving around, the levels have dropped. We can keep the levels at a safe spot by riding bikes more or going on more walks instead of driving cars unless we need to. We can also cut down some factories if possible or limit the time they are working.

# data[].attributes.body
During quarantine, a lot of places were shut down, leading to less work that contributed to air pollution. This means that there was a lot less PM2.5 in the air because people weren't doing some things, like working in factories or driving cars. In order to keep the decreased air pollution going, things like these that harm the air quality need to be kept to a minimum.

# data[].attributes.body
With this of the pandemic the PM2.5 as we have already said that they are like fine particles of any element (be it ashes, dust, cement, etc.) this pm2.  5 It pollutes the air and what it causes is an affection to people in the respiratory tract.  The experiment that China did to see how PM2.5 decreases this contamination worked for them since in recent months the graphs and statistics show a drop in PM2.5 in the country, and this is because in quarantine people are kept  in their houses and they do not use most of their cars, since cars and planes are one of the main causes of PM2.5 and not only cars or planes, the same factories produce that too, which is why in China there are too many  factories, then it must be said and I think that of those factories 50% must be closed due to the pandemic, which has also caused air pollution to drop a lot.

# data[].attributes.body
When this pendemic broke out many factories and buisnesses were shut down. This caused less air pollution due to less traffic. If we keep it like that and have people ride their bikes so we dont increase those levels. Overall, keeping a minimum of cars driving will leave those levels low.

# data[].attributes.body
The solution is to build the factories in the desert or in places that there is no people in it.
Another solution is to ride a bike or a scooter or anything that doesn't need gas because cars are very harmful too.

Before Covid - 19 in Wuhan, China and other big cities around the world, the PM2.5 levels were very high and unhealthy for lots of people to breathe in. It has affected many of those who have health problems and may have increased their risks of catching other sicknesses. The causes of the high PM2.5 levels were mostly from cars, factories, airports, etc... but ever since places were put on lockdown, the PM2.5 levels have decreased drastically! The travel rates have went down causing less fuel and other particles to get through the air and mostly everybody stayed home, which is a good thing for the environment and themselves. The stay at home order has caused a major change in the environment in a good way, but the PM2.5 levels will most likely go up again once quarantine is over :( People could resolve this problem by taking public transportation and riding bikes, or even walking!

# data[].attributes.body
Some places in the world,such as Wuhan china, have alot of industrial and transportation caused PM2.5 particles in the air. Because of the travel restrictions/bans set because of the Covid-19 outbreak, the amount of air pollution has gone down substantially. This shows how air pollution can be easily reduced, or even fixed, with the more widespread use of electric vehicles. When Electric do not produce any emissions,and when they are charged from power sources that are of renewable energy, it is a win win.

Before all of this corona and quarantine, the air quality was super low. But as quarantine has started to impact everyone’s life the air quality was gone up dramatically. One solution to making the air quality even better is to come up with a different way to use energy and get things done in the world besides using unhealthy energy. This way you can work and get things done and also have safe and healthy air to breathe

# data[].attributes.body
a way i think we could fix pollution by using bikes more and cutting down on the gasses coming off of cars and other things, also we could start cutting down on those greenhouse gasses because those have a big effect as well, all these things are killing animals, birds, etc. and if we don't make a change bad things could come because an effect of pollution results in global warming and the effects of global warming is that in antarctica glaciers and other large amounts of land are melting giving polar bears and penguins no places to live and that leads to extinction and species dying out so we need to make a change now or it might be to late

In Wuhan, China before Covid-19, the PM2.5 levels were at its worst. The air was unhealthy to breathe in and would have an effect on the people's health. The cause of this was due to burning fuel such as factories or cars, making the air worst. Since Wuhan went into quarantine, the air has drastically improved. Since there are less people going out, the less fuel is being burned. The quarantine has had an astonishing impact on the environment but will most likely return back to having high PM2.5 levels after the quarantine is over. A solution would be to limit the amount of fuel factories use and to limit how much of something they're going to produce

# data[].attributes.body
Before quarantine, the air quality wasn't good and there was a lot of pollution. This is because there were many more cars driving around, a lot of factories open, more planes flying around, etc. Because of the virus, most stores and businesses were closed, there were less people driving because you were only supposed to leave your house if it was necessary so people barely left their houses. As things got better people would go on walks or ride their bikes which doesn't cause any pollution. Since majority of people were in their house there was less pollution which made the air quality better.

We all know that China is one of the most populated cities in the world and that is why the Asian giant suffers from air pollution. Before covid 19 this country already had a big threat. A change could be made trying to use more the bicycles and reducing the activities of the vehicles since they are the one of the great causes of contamination. You can still make a change but it has to be as soon as possible.

# data[].attributes.body
Before the stay at home orders the PM2.5 levels were very high. During quarantine the levels lowered which is good. During this the levels were lower because there was less travel which means that there was less pollution. I think that some solutions to help would be to take the bus, carpool, walk to where you are going, or even ride your bike.

# data[].attributes.body
Before quarantine the PM2.5 levels were dangerously high but now that everyone is isolated no one is working in the factories or driving a car around. I believe to decrease the amount of PM2.5 levels is to find a way to create less smog or soot in factories or anywhere else. This will create a healthy environment where everyone can have fresh air and clear skies.

# data[].attributes.body
Before the quarantine in the reading said that in china in wuhan the environment of PM2.5 is very polluted and decreased considerably but the bad thing that now that everything returns to normal again the contamination will rise but the good thing is that the planet rest for a time from contamination.

i feel like we should start using more evermantal friendly energy then burning fossil fuel.And to do this we should trust private companies that are thing to do this

When we didn't have quarintine the PM2.5 levels were high. Now that everyone self quarintined themselves the PM2.5 levels have lowered. This is good because there is less pollution in the air. A solution that can help a lot is if people start driving electric cars.

# data[].attributes.body
to keep the pollution levels from going back up, i think everyone should continue the habits that we have now for covid 19 and not go to the grocery store as much and cut down on not necessary trips to places. Or alternatively still go to those places that we want to go to but dont need to go to, but use alternative methods of transportation so cut down on emmisions.

# data[].attributes.body
In the past the levels of PM2.5 were very high on average causing dangerous pollution to be in the air which the people were breathing, this can cause many problems especially with the lungs.  In order to combat this as we have seen due to the lockdown causing less emissions we need to find ways to lower emissions to a level which is closer to that of the lockdown.  I believe we could do this by putting stricter laws on the major company factories which reside in china then we would need to use less cars and use the train system or other ways of transport which use less fuels or getting more electric cars

Before quarantine, the air quality was terrible in many places. PM2.5 levels were high in alot of areas and that isn't good since it is one of the most harmful pollutants. These terrible air qualities can cause respiratory problems in some people and that is not what we want. When the stay at home orders were assigned, many people followed the guidelines to prevent COVID-19 and many people starting noticing the drastic differences in the air quality because people weren't outside as much as they used to be. The fog in many cities cleared up and the sky became visible. We should maintain the healthy air qualities we have at this moment. In order to do that, we should find different ways of transportation like riding bikes or walking. We should use cars less often because they emit harmful toxins into the air, such as hydrocarbon, which can cause the air to be poor in quality. When everyone starts taking these steps, the earth will be much cleaner and people will also feel much healthier.

# data[].attributes.body
To keep the PM2.5 levels low we should all stay quarantined for a bit because before the quarantine the levels were dangerously high. Now that here is a lockdown and no activity the air is starting to get better but will most likely return back when this is over. The cause of these high PM2.5 is probably transportation, airports, factories and because of lockdown nobody is out using transportation, airports, or working.

# data[].attributes.body
before quarantine the PM2.5 levels was higher than during quarantine. during quarantine less toxins were released into the atmosphere.  limiting ourselves from using stuff that pollutes the air is the best solution.i think the best solution is for people to stop being dumb

Predating the Stay home orders there were ludicrous amounts of greenhouse gasses and emissions from vehicles going into our atmosphere, the result in this is the production of PM2.5 . To cut down on the levels of particulate matter we should utilize more efficient fuel sources and not burn up as much fossil fuels. Reducing the excessive use of vehicles such as cars and planes, would furthermore preserve the air quality levels. Fuel sources that would benefit the environment, consist of electric power, or other renewable propellants.

before corona the air quailty wasn´t that good or it was high but when the stay at home orders were put in place and we were quarantined it was lower which meant it was better , which is saying just to stop using everydays things for a while less cars less polution less factory bussiness better air quailty.

Before the shut down from covid 19 the air quality in China was really dangerous. There were dangerous levels of pm2.5 . All of the factories and people commuting made the air quality really poor and unsafe. Since the shut down the levels have gotten better and are more safe. To keep these levels closer to where they are people need to learn about how these thing affect the air and make a conscious effort to use methods that produce less things  that are harmful in the air. Factories should use greener technologies and they should be better rewarded for this. People also should find better ways to commute like switching to vehicles better for the air or  using harmful vehicles  less often

Before covid-19 took a big impact on the world the levels of PM2.5 were very very high.That was caused by all of cars,buses,fast food places and other businesses. As covid-19 temporaily "shut the world down" there was much less people traveling so less cars were being used also alot of places shut down to prevent the virus for spreading witch helped the PM2.5 levels lower by a lot.so if we want to keep the air healthy and clean and the the PM2.5 levels low for much longer then just while corona virus is going on we need to limint busniess and ride bike and walk places instead of using cars as much so we can keep the air and world healthy!

# data[].attributes.body
Before quarantine the PM2.5 levels were dangerously high which resulted in many things happening to our glob but after the spreed of Covid-19 and there was less people traveling and riding vehicle which drooped by 7% compared to the other years that is a big drop for us and when I saw that I was like we shod keep it low so instead of always asking to get a rid I started riding a bike and or walking and I've been trying to keep helping the planet so in conclusion because of the pandemic the PM2.5 levels have drooped significantly and we hope that it keeps drooping until the Earth is some what clea.

Before covid-19 the levels of PM2.5 were very high. But because of the virus there wasnt as much pollution in the air. for example during quarantine less people are outside, and theres not as many cars or busses on the road either. to keep the air healthy we need to be riding our bikes if were going somewhere close instead of using a car, or we can walk places
